In the high-end manufacturing fields such as nuclear power equipment, precision hydraulic systems, high-end instruments and meters, as well as aviation special equipment, the equipment is constantly exposed to extremely complex working conditions including high temperatures, radiation, high-pressure impacts, and high-frequency damping movements. These conditions place extremely high demands on the thermal stability, radiation resistance, damping stability, and long-term safety of the medium oil. Ordinary industrial silicone oil and lubricating oil have deficiencies such as insufficient high-temperature resistance, easy aging under radiation, poor high-pressure deformation, and susceptibility to corrosion of sealing components, making them unable to meet the long-term stable operation requirements of special equipment. Product BJ710, a benzyl silicone oil, as a high-performance single-benzyl-methyl-benzyl poly-siloxane polymer, with its ultra-high radiation resistance, high flash point, low volatility, and high compressibility damping characteristics, fills the domestic gap in medium oil for high-end special conditions and becomes a core dedicated silicone oil product for nuclear power, precision damping, high-temperature heat transfer, and high-pressure buffering fields.
Product BJ710 benzyl silicone oil is a pure colorless transparent liquid. It is synthesized using a mature single-benzyl structure synthesis process, with high purity, stable components, no impurity precipitation, and highly unified physical and chemical properties. It is suitable for the matching use of various high-precision equipment. The product has industry-leading safety and thermal stability indicators. The open cup flash point is ≥ 300℃, the ignition point exceeds 343℃, the autoignition temperature is as high as 487℃, it is flame retardant and non-flammable, and there is no risk of fire or violent evaporation under high-temperature conditions. The equipment's continuous operation under high-temperature conditions has a significantly improved safety. The pour point is as low as -22℃, it has strong adaptability to both high and low temperature environments. It does not solidify at low temperatures or gel at high temperatures. It can maintain a stable fluid state in a wide temperature range. At the same time, the volatile content of the oil is extremely low. After being baked at 250℃ for 4 hours, the volatile amount is only 3.0%. Long-term high-temperature operation does not cause loss or carbon accumulation, effectively extending the equipment's maintenance cycle.
As a single-benzyl structure special silicone oil, product BJ710 has the industry's top radiation resistance performance. The radiation resistance value can reach 1.7×10⁸ rads, which can long-term resist high-energy radiation and environmental erosion. The oil structure does not decompose and its performance does not deteriorate. It perfectly adapts to radiation exposure conditions such as nuclear power plants, radiation laboratories, and special military equipment, solving the problems of radiation aging, failure, and deterioration of ordinary oil products. At the same time, the product has extremely strong chemical inertness. It has no corrosiveness throughout the process and will not cause corrosion damage to metal valves, pipelines, and precision components. It will not damage pressure reducers, valves, and precision instruments' matching sealing materials. It does not swell, harden, or corrode the sealing components, ensuring the long-term stable and reliable sealing system of the entire equipment.
High compressibility and precise damping performance are the core differentiating advantages of product BJ710. The product has excellent pressure deformation adaptability. Under different high-pressure conditions, the volume modulus is stable and controllable. The compression deformation laws under 5000psi, 10000psi, and 20000psi gradient pressures are controllable, and the damping output is uniform and stable. It can precisely adapt to the damping, buffering, and anti-shake requirements of hydraulic lightning arresters, high-pressure buffers, reciprocating damping mechanisms, and precision motion instruments. Compared to ordinary silicone oil damping oil, this product has a viscosity temperature coefficient of only 0.79, with minimal viscosity fluctuations due to temperature changes. Regardless of high-temperature operation or low-temperature standby, the damping force is always balanced and stable, completely solving the problems of temperature drift jitter and buffer failure of precision instruments and high-pressure equipment.
